Halts & Listings
Halts & Listings tracks trading halts, the Reg SHO threshold list and listing status changes in one place. A halt usually means news is coming or something is wrong, and either one can gap a stock hard when it reopens.
Halts, the Reg SHO threshold list and listing changes side by side.
The top of the page
The ticker filter at the top (Filter by ticker (e.g. GME)) applies to every section. Below it, four stat cards: Halted right now, Halts · last 7 days, On Reg SHO list and Listing changes.
Halted right now
Halts with no resumption yet that started within the last 7 days.
Halt history
A table of halts, newest first, 15 per page:
- Status: HALTED, Resumed, or "—" for older halts where the resumption wasn't captured
- Halted (ET), Ticker, Company, Reason, Resumed
Reason codes are shown in plain English. The common ones:
- T1 News pending, T2 News released, T3 Reopening soon
- T5 Volatility pause (more than 10% in 5 minutes)
- T12 Info requested
- H4 Non-compliance, H9 Filings overdue, H11 Regulatory halt
- H10 SEC suspension, the most serious kind
- LUDP / M Volatility pause (automatic limit-up/limit-down or volatility pause)
- MWC1, MWC2, MWC3 Market-wide halt
TIP
A T1 or T2 halt is usually a news event and tends to reopen with a gap. H-codes, and H10 above all, point to regulatory trouble. Volatility pauses are routine and usually clear within minutes.
Reg SHO threshold list
